The United Nations has proclaimed 2019 the International Year of the Periodic Table of Chemical Elements - coinciding with the 150th anniversary of Dmitry Mendeleev's published periodic table in 1869 - to raise global awareness of how chemistry provides solutions to global challenges in energy, education, agriculture and health.
